Liospiriferina sicula (GEMMELLARO, 1874) — Seven specimens were collected at three localities. The Mondsee specimen is badly preserved with very deep sulcus. This species is very similar to L obtusa but it is larger and it has larger and wider uniplication. SlBLÍK (in BÖHM et al. 1999) regarded these two species synonymous. This opinion is not followed in this paper and later SlBLÍK (2002) himself mentioned also both L sicula and L. obtusa from the Northern Calcareous Alps. Detailed systematic description was given by DULAI (1992 and in press). Liospiriferina zignoi (Dl STEFANO, 1891) — Only one very small juvenile specimen occurred at Mondsee locality. The brachial valve is flat, while the pedicle valve is very convex. The area is flat and the angle between the the interarea and the commissure is about 60—70°. The rounded rectangular outline is slightly oval; width is larger than length. This is the first record of this species from the Northern Calcareous Alps. Orthotoma apenninica (CANAVARI, 1883) — Only one small specimen was found at the railway station upper terminus of Schafberg. Both valves are very flat, the convexity of the pedicle and brachial valve is the same. The outline is oval and width is slightly larger than length in CANAVARI'S (1883) original description. The Schafberg material is similar to this form. It was also mentioned from the Pliensbachian formations of the Transdanubian Central Range (VÖRÖS 1997). This is the first record of this species from the Northern Calcareous Alps. Orthotoma sp. — Five small specimens were collected at Mondsee locality 7 . Their form differs from O. apenninica in the outline that is ovate in the Schafberg specimens, being longer than wide and the valves are not so flat. Lobothyris andleri (OPPEL, 1861) — Twenty specimens were found along the Schafberg slopes and at Mondsee. AGER (1990) and ALMÉRAS & FAURÉ (2000) studied Lobothyris genus in detail and they synonymized SuCIC-PROTIC's (1971) several new genera with Lobothyris. BÖHM et al. (1999) showed a L andleri specimen with rounded outline, while the Hungarian Hettangian specimens were more elongated and subpentagonal in outline (DULAI 1993). We have also found specimens with rounded outline along the Schafberg slopes. The studied Schafberg specimens are generally large and both valves are slightly convex. Both wider and narrower forms occurred at Mondsee. Detailed systematic description was given by DULAI (1993 and in press). Lobothyris delta (NEUMAYR, 1879) — Only one specimen was found on the slopes of Schafberg. This species has already mentioned from several localities of the Northern Calcareous Alps (e.g. Breitenberg, Eiberg) by SlBLÍK (1999). It is similar to L andleri but its outline is more elongated. The pedicle valve is more convex than brachial one. The beak of the Schafberg specimen is not so strong than it was shown by SlBLIK (1999). Lobothyris punctata (SOWERBY, 1812) (Plate VII: 18-20) — Eight specimens occurred at three collecting points along the slopes of the Schafberg. Very variable form with several described subspecies; this variability was demonstrated by GEYER (1889) and PARONA (1885). L andleri also was regarded earlier as subspecies of L punctata. It is smaller and not so convex than L andleri. It has more or less oval outline. Detailed systematic description of the species was given by DULAI (1992 and in press). Viallithyris gozzanensis (PARONA, 1880) (Plate VII: 21—23) — Eight specimens were found at one collecting point of the Schafberg slopes. Relatively large-sized, subpentagonal form with rather convex valves. The anterior commissure is rectimarginate or slightly sulcate. VÖRÖS (1978) ranged this species into his newly described genus Viallithyris. BÖSE (1898) mentioned V. go^anensis from several locality of the Schafberg area. Linguithyris aspasia (ZlTTEL, 1869) — This species was found only at one locality 7 (Mondsee) but it was relatively frequent there. The Mondsee specimens from the Semicostatum Zone are small to medium-sized: they are generally larger than the Hungarian Early Sinemurian material from Lókút Hill or Vöröshíd quarry (Dulai 1992 and in press; Bucklandi Zone), however smaller than the Pliensbachian forms of the Transdanubian Central Range. It seems that the evolution of this species can be characterised by a more or less continuous size increasing. Several authors mentioned the similarity between L aspasia and L nimbata. These species were regarded as synonymous by the author (DULAI 1992). According to PROSOROVSKAYA & VÖRÖS (1988), the author of L aspasia is ZlTTEL (1869) [not MENEGHINI (1853)]. If this subjective synonymy were accepted, L nimbata would have priority. However, the name of L aspasia is much more widely used and known, therefore it might be suggested for status of "nomen conservandum". Formerly, this species has been ranged into several genera (Terebratula, Waldheimia, Pygope, Glossothyris, Propygope, Nucleata) but recently Linguithyris is generally accepted. The species nimbata was regarded as Rhapidothyris with question mark by SlBLÍK (2002) Detailed systematic description was given by DULAI (1992 and in press). Zeilleria alpina (GEYER, 1889) — It is a widespread species in the Schafberg area: seventy-six specimens were found at seven collecting points. Some of them are small, juvenile specimens. SlBLÍK (1993) synonymized Zeilleria baconica complanata subspecies, described by BÖCKH (1874) with the studied species. However, the investigation of the inner morphological characters of the Hungarian Hettangian specimens refers to Lobothyris (see DULAI 1993). SlBLÍK (1993) identified a specimen with small sulcus as belonging to this species. However, the name could be applied only for specimens with rectimarginate anterior commissure. Detailed systematic description was given by DULAI (1992 and in press).
